“…Overall, tolerance to trampling, i.e. the ability of vegetation to withstand a cycle of disturbance and recover, seems primarily a function of stature, erectness, and growth form (Cole 1995;Sun and Liddle 1993). The most tolerant plants are annuals, caespitose graminoids, rosette hemicryptophytes, and geophytes, whereas the least tolerant plants are the chamaephytes.…”

“…The most tolerant plants are annuals, caespitose graminoids, rosette hemicryptophytes, and geophytes, whereas the least tolerant plants are the chamaephytes. According to Cole (1995), tolerance is explained more by plant morphological traits than by site characteristics, even though relatively flat sites are less affected than sloped sites (Weaver and Dale 1978).…”

“…In addition to herbaceous species, a dense carpet of mosses, lichens, and chamaephytic species forms a short prairie with high total cover (Tortulo-Scabiosetum). The flat topography and the presence of many chamaephytic species enhance resistance to mechanical disturbance such as trampling but, as characteristics that support the ability to resist trampling damage differ from those that allow plants to recover quickly (Cole 1995), once damaged, the woody stratum can regenerate only very slowly. Therefore, because of trampling, tolerant herbaceous species can replace sensitive dwarf shrubs.…”

The response of plant community diversity to alien invasion: evidence from a sand dune time series

This study examines the process of invasion of coastal dunes in north-eastern Italy along a 60-year time series considering alien attributes (origin, residence time, invasive status, and growth form strategy) and habitat properties (species richness, diversity and evenness, proportion of aliens, and proportion of focal species). Vegetation changes through time were investigated in four sandy coastal habitats, using a fine-scale diachronic approach that compared vegetation data collected by use of the same procedure, in four time periods, from the 1950s to 2011. Our analysis revealed an overall significant decline of species richness over the last six decades. Further, both the average number of species per plot and the mean focal species proportion were proved to be negatively affected by the increasing proportion of alien species at plot level. The severity of the impact, however, was found to be determined by a combination of species attributes, habitat properties, and human disturbance suggesting that alien species should be referred to as ''passengers'' and not as ''drivers'' of ecosystem change. Passenger alien species are those which take advantage of disturbances or other changes to which they are adapted but that lead to a decline in native biodiversity. Their spread is facilitated by widespread anthropogenic environmental alterations, which create new, suitable habitats, and ensure human-assisted dispersal, reducing the distinctiveness of plant communities and inducing a process of biotic homogenization.

“…In terrestrial habitats, herbaceous plant species that are low-growing, have tough leaves, and form mats or tufts are generally more resistant to trampling than other growth forms (Cole 1995b). Terrestrial grasses are more resistant to trampling than some forest plant species, such as leafy, stemmed forbs (Cole 1985).…”

Human wading in shallow coastal waters is a common activity that inherently involves trampling of the substrate. An experiment was conducted in Thalassia testudinum seagrass beds in Puerto Rico to determine how seagrass and associated mobile fauna respond to this anthropogenic disturbance. Three trampling intensities were applied to replicate seagrass beds throughout a 4 mo period. Seagrass biomass was inversely related to trampling intensity and duration. There was moderate recovery in the trampled areas 7 mo after the last trampling event. Intense levels of trampling resulted in decreased shrimp abundances, especially for Thor manningi. Fish abundances and composition of shrimp and fish assemblages did not change significantly after 4 mo of trampling. T. testudinum beds with softer substrates lost more seagrass biomass as a result of trampling than seagrass beds with firm substrates, suggesting that substrate firmness can modify disturbance effects. Educators and resource managers should limit trampling by large groups, or confine it to small areas with firm substrates, and researchers should be mindful of artifacts arising from trampling in and around sampling areas.

“…Cole (1995) examined plant responses to human and herbivore trampling and found that trampling creates a characteristic plant community dominated by species whose morphology gives them a certain tolerance to bruising and compression. Thus, herbaceous species such as valerian and yarrow would be more impacted by trampling than woody species such as kinnikinnick and Oregon grape.…”
